remediation liner Articles

ABSTRACTLining is being used by the utility industry as a cost effective solution to rehabilitate utility lines. Many types of liners, such as, cured-in-place-pipe (CIPP), fold and form PVC, deformed & reformed HDPE, etc., are being used to restore structural integrity of deteriorated pipes and to reduce inflow/infiltration. Most of the lining installation is carried out without any problem, ...

Asarco, Inc. Omaha, Nebraska, USA For more than a century, the former American Smelting and Refining Company (Asarco) operated a lead refinery on the banks of the Missouri River in Omaha, Nebraska. Plant closure in 1997 presented an opportunity to reclaim the riverfront as public space. Led by HDR, this successful transformation became the largest voluntary clean up ...

The Stevens Hydra Probe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The need for clean, healthy rivers, lakes and streams has stimulated research to develop ...

PROJECT: Patterson Plank Road Brownfield Remediation LOCATION: Patterson, New Jersey PRODUCTS: BENTOMAT® SDN BACKGROUND: This New Jersey brownfield was formerly the site of a chemical recycling facility. CHALLENGE: The soil at the site was heavily contaminated, and off-site removal would have ...

THE PROBLEM In 1990, 4500 m3 of silty sand/soil contaminated with mineral oil (diesel) to a level of 1500 ppm was treated on-site (Port of Antwerp) at the request of the client. OUR APPROACH On reviewing both the site and the scope of the project it was clear to Nordevco staff that the most cost effective and efficient approach would be to treat the soil in a ...

The Problem Staff at a major four-star resort outside St. Thomas in the US Virgin Islands spilled diesel fuel and kerosene during the transfer from a tanker truck to on-site storage tanks. Approximately 67.3 m3 of soil having an average concentration of 12,000 ppm was contaminated. Because there are no treatment facilities on the Island, the resort was facing significant costs to transport ...

Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, pose environmental threats to ground water resources worldwide. DNAPL site characterization method performance comparisons are presented in a companion paper (Kram et al. 2001). This study compares the costs for implementing various characterization ...

Project: Zidell Marine Corporation Sediment Cap Location: Portland, OR Products: Reactive Core Mat filled with Granular Activated Carbon (GAC) and Apatite II Background: Cleanup is required for land which was contaminated with a variety of chemicals as a result of ship construction, ship breaking, and barge construction at a ...

TERRAM Erocell has been used on a significant earthworks contract designed to help safeguard the local environment around the Milford Haven Oil Refinery in South West Wales The contractor, Llanelli based Quantum, have been carrying out remediation works on an existing bund that lies between the site boundary and a storage lagoon used to retain potentially contaminated drainage water from the site ...

A Tyre Aggregate (TA) is made from scrap/waste rubber tyres. Four types of tyre aggregates are classified, namely the coarse-grained, fine-grained, random and composite tyre aggregates. Applications of these tyre aggregates are varied, but they are often used as geomaterial fills and highway-pavement components. More recently, TA has found application in geoenvironmental engineering. This paper ...

Most of the landfills in developing countries do not have any liner at the base, or a drainage layer or a proper top cover, which results in the potential problem of groundwater/surface water contamination due to the leachate. Hence, to decide whether the leachate is to be collected and treated, or may be allowed to discharge into the adjoining soil or public sewer or surface waterbody, it is ...

The question of how much landfills leak might be the most contentious question in the solid waste industry and the one with the most elusive answer. Leakage can be predicted using models of varying levels of sophistication, but modeling relies on accurate data for hole frequency and size. Published statistics for hole size and frequency vary widely and most of the published data is drastically ...

Edison, New Jersey, USA Project Bioremediation of TNT & DNT in Homogenized Soil Summary DARAMEND® bioremediation technology was applied at pilot scale to approximately 100 tons of soil from the former Raritan Arsenal in Edison, New Jersey. Area 4 at the Raritan Arsenal was formerly used as a high explosives salvage and melt-out area from World War I ...

Maximizing Compostables At The Olympics THE GOVERNMENT of New South Wales, Australia passed the Waste Minimization and Management Act in 1995, setting a reduction target of 60 percent. One indicator of how much commitment and infrastructure are available to reach this goal will be the success of the overall organics recycling achievements at the 2000 Summer Olympic Games in Sydney (see ...

Project In 2008, the City of Altanta faced a large problem: the single-lane road that provides the only entry point to its SWAT team training center was likely to be lost completely to erosion. Although the road had been lined with concrete barriers as a stop-gap measure, it was clear that more substantial action was required to save it. Because the road is situated on a narrow ...

Common treatment technologies for nonhalogenated SVOCs in soil, sediment, and sludge include biodegradation, incineration, and excavation with off-site disposal. All types of biodegradation, both in situ or ex situ, can be considered to remediate soils: in situ bioremediation, bioventing, composting, controlled solid phase, or landfarming. Slurry phase biological treatment is also applicable but ...

Common treatment technologies for halogenated SVOCs in soil, sediment, and sludge include biodegradation, dehalogenation, incineration, and excavation with off-site disposal. All types of biodegradation, both in situ or ex situ, can be considered to remediate soils: in situ bioremediation, bioventing, composting, controlled solid phase, or landfarming. Slurry phase biological treatment is also ...
